"We do not want any interruption," said Director of Surgery Irela Morris.

Distraction aside, Morris described another serious reason.

"You use the cell phone; you put it in your pocket. Now you forget you used that cell phone in a dirty environment, you put it in your pocket, now you go to lunch," Morris said.

Cross-contamination is an invisible, chronic threat at healthcare facilities and cell phones only add to the risk, especially in certain surgical rooms, according to surgical tech Mary Ann Cerino.

"Working in endoscopy, you certainly don't want your phone down in endo," said Cerino, "Oh, it'd be very easy (to spread infection) if you don't take the proper precautions."

Medical instruments at Bonita Community Health go through a three-step cleaning process: handwashing, followed by going through an automatic washer using extremely hot water, and finally, the medical instruments are exposed to 270-degree heat.

Ultraviolet robots are another germ-fighting tool used at larger hospitals like Lee Memorial Health System.
